Robin from Fire Emblem: Awakening. Found lying in a field without their memories, Prince Chrom rescues them. Robin becomes an invaluable asset as Chrom's tactician and close ally.

I may come back to post alts for female Robin, as well as the Grandmaster class outfit and Brave Robin from Fire Emblem Heroes, but I haven't made any of these yet.
